Baffling system designed for acoustic suppression

ABSTRACT

A silencer device for acoustic suppression may include a first housing section; and a second housing section detachably connected to the first housing section. The first housing section may define a first baffle chamber and the second housing section defines a second baffle chamber. The silencer device may include a baffle device positioned within the first baffle chamber and the second baffle chamber.

FIELD OF THE INVENTION Background

Reciprocating pumps utilize a suction manifold and a discharge manifold for moving the media that is being pumped. These manifolds are equipped with valves that assist the reciprocating pump in media delivery to the piston or plunger chamber. When the valves are opening and closing, this creates a high frequency energy wave that is contained in the pumped media. This high frequency energy wave is commonly referred to as acoustic energy or harmonics, and they are damaging to the pump and piping system. If acoustics aren't properly filtered out of the system, this will create premature failures on pump expendables as well as the piping components.

DETAILED DESCRIPTION

Reciprocating pumps utilize a suction manifold and a discharge manifold for moving the media that is being pumped. These manifolds are equipped with valves that assist the reciprocating pump in media delivery to the piston or plunger chamber. When the valves are opening and closing, this creates a high frequency energy wave that is contained in the pumped media. This high frequency energy wave is commonly referred to as acoustic energy or harmonics, and they are damaging to the pump and piping system. If acoustics aren't properly filtered out of the system, this will create premature failures on pump expendables as well as the piping components. The present invention solves this problem.

The present invention utilizes an inline, multiple chambered, baffling system positioned between the suction manifold and the discharge manifold to absorb and reorganize high frequency energy waves or acoustic energy. The inline design forces the acoustics into the baffling chambers then restrict and redirects the flow of media, producing a pressure drop across the baffling and absorbing acoustic energy. The discharge of the baffling system produces a smoother, reorganized harmonic Signature safe for the pump and piping system.

FIG. 3 illustrates a top view (which may be a mirrored bottom view) of the baffle housing 101 of the silencer device 100 of the present invention. The baffle housing 101 may include a first housing section 103 and a mirrored second housing section 105 which may be detachably connected to the first housing section 103 by a fastener 151 for example an opposed pair of threaded bolts and nuts or other appropriate fasteners. The first housing section 103 and the second housing section 105 may include a first baffle chamber 107 and a mirrored second baffle chamber 109 respectively which may extend through the baffle housing 101. The first baffle chamber 107 may extend through the first housing section 103 to the first opening 111, and the second baffle chamber 109 may extend through the second housing section 105 to the second opening 113 where the first opening 111 and the second opening 113 may connect to the suction manifold and the discharge manifold (not shown) respectively. The first baffle chamber 107 and the mirrored second baffle chamber 109 may include a wide portion 131 and a narrow portion 133 which may connect to the wide portion 131 and the first opening 111 and the second opening 113 and may connect to the wide portion 131 by a shoulder 135.

The wide portion 131 may be connected to a baffle device 141 which may include a pair of opposing first baffle 143 and a second baffle 145 which may be connected by a baffle connector rod 147. The periphery of the first baffle 143 and the second baffle 145 may extend to the surface of the first housing section 103 and the second housing section 105 respectively. The surface of the first housing section 103 and the second housing section may be defined by the wide portion 131 of the first baffle chamber 107 and the second baffle chamber 109.

The first housing section 103 and the second housing section 105 may include apertures 115 for connection to the suction manifold and to the discharge manifold. Additionally, the first housing section 103 and the second housing section 105 may include a groove 149 which may extend around the periphery of the first and second housing section 103, 105 in order to facilitate the application of a gasket to seal the suction manifold and the discharge manifold. FIG. 10 illustrates a detail of the groove 149.

FIG. 2 illustrates the first housing section 103 (the second housing section 105 may be a mirror of the first housing section 103) which may include the first baffle chamber 107 which may include a wide portion 131 and a narrow portion 133 connected by a shoulder 135. The narrow portion 133 may include an opening 111 to allow fluid to either enter or escape from or to the suction manifold/discharge manifold. A groove 149 may extend around the opening 111 to provide for a gasket to seal the housing section 103 with either the suction manifold or discharge manifold. A fastener 151 may extend through the first housing section 103 and the second housing section 105 to connect the first housing section 103 to the second housing section 105. These fasteners 151 may extend around the periphery of the silencer device 100.
